GE IC697VDR151 Discrete Input/Output Module

Discrete Input/Output Module is a common input/output module in industrial automation control systems, which is used to receive and send discrete signals, that is, signals with only two states, such as high (H) and low (L). Discrete input/output modules are usually connected to devices in industrial sites, such as sensors, switches, actuators, etc., to receive the discrete signals sent by these devices and convert them into a computer-readable data format. At the same time, the discrete input/output module can also convert the output signal of the computer into a discrete signal to control the operation of the field equipment.

According to different types and uses, discrete input/output modules can be divided into digital input/output modules, analog input/output modules, photoelectric isolation input/output modules, etc. Among them, the digital input/output module is used to receive and send binary signals, the analog input/output module is used to receive and send analog signals (such as voltage, current, etc.), and the photoelectric isolation input/output module uses photoelectric isolation technology, which has higher anti-interference performance. In addition to different types of discrete input/output modules, there are various brands of discrete input/output modules, such as Siemens, Schneider, OMRON, etc., these brands of discrete input/output modules have different specifications and performance characteristics, which can be selected according to actual needs.
